Do Truthers regard the air traffic controller recordings as fake?

From the moment the 4 planes that crashed on 9/11 departed the airport, their paths were tracked and recorded. There were countless witnesses who saw flight 175 crash into the WTC-and plane debris was scattered everywhere. yet Truthers wave away eye witnesses accounts saying nobody really saw planes crash into the towers. How does one have intelligent conversations with such people? How does one help them see reason?
Here is a good video with the ATC recordings:
